IMPROVEMENT IN BEER-FAUCETS.

Specification forming part of Letters Patent No. 53,692, dated April 3,1866.

Adevice for foaming heer and other liquids artificially previous totheir being drawn, so as to be able to cause the foaming of the liquidtoany degree desired within a common faucet, and that immediately after,when the pin of the faucet is turned so as to open, the liquid will flowfrom itin a cream y and gaseous state sufficient to fill two or threeglasses without renewing the operation; and I d o hereby declare thatthe following is a full and exact de- Scription.

'Ihe nature of my invention consists in having a hollow room or chamberinside a common faucet, between the cross-pin and the end which tapsinto the barrel. The hole in the faucet running through this chamberwill constantly keep it filled with liquid, so that when it is requiredthe foaming operation can be performed, which is done by placing down inthe chamber a kind of syringe with a ring of line holes around thelowest end of the tube, this end being fastened to the bottom of thechamber by means of a screw. rIhe upper end of the tube with thepiston-rod extending outside is tightly fastened on the top of thechamber, so as to prevent any escape of liquid. The head of thepiston-rod extending out of the tube, and running parallel with the headof the cross-pin, enables the same hand to handle both of them withfacility.

The up-and-down movement of the piston will naturally force in and outof the tube through the small holes all theliquid contained in thechamber, and convert it into a foaming substance.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Figure 1 is a cross-section of the faucet.

Same letters refer to those on Fig. l.

I construct my faucet on the ordinary plan, only using a swelling orshoulders, B B, on each side of its body, between the cross-pin A andthe small end of the faucet, for the purl pose of giving more depth tothe chamber or reservoir (l, which I make by boring one or more holes,according to the capacity intended to give the said chamber. The hole isbored from one shoulder B B to the other and across the hole D in thefaucet. Into this chamber I fasten a kind ot' syringe, E, which runsthrough it parallel with the cross-pin A. This syringe is kept fast inthe chamber by the screw and nut F, which work as a bolt under thebottom G, so that when screwed fast both top and bottom H G will be setair-tight against the shoulders B B and between the extending base ofthe syringe I and the said screw and nut F, and hold together as one.

Ihe piston-rod K, which runs out above the cover, is connected to thepiston L by any suitable means. This piston is made of metal, of theshape of a spool of thread, surrounded by a soft substance, so as to ttnicely the inside of the tube.

To facilitate the handling, I make the arm of the cross-pin turn to theright to open and l to the left to close.

What I claim as my invention, and desire to secure by Letters Patent,is-

Foaming beer or other liquids to any degree desired previous to theirbeing drawn, by constructing a hollow room or reservoir within anordinary faucet, between the crosspin and the end to be tapped in thebarrel to be operated into by the syringe E, for the purpose and in themanner set forth.
